WINDOW-BLIND.

SPECIFICATION forming part of Letters Patent N 0. 395,902, dated January 8, 1889.

Application filed An us. 2, 1888. Serial No. 281,757. (No model.)

The slats of wiinlow-blinds as heretofore made have usually been cminected to a vertical operating-rod by staples, and in some instances a band of metal has passed around the individual slats, the ends of which band have been connected by an eyelet and the vertical rod has been connected by staples to these eyelets. In all of these cases the slats in time become loose and the wind will open and shut the same and leave them in a position that may admitsunlight or too much air 1 at a time when it is desired to have the slats closed.

The object of my invention is to provide a fastening device for the slats and to provide metal strap surrounding the entire slat. Fig.

2 is a sectional plan of the same. Fig. 3 is an elevation cndwise of a number of slats, showing the metal strap as surrounding the reduced portion of the slats at one end; and Fig. 4 is a sectional plan of the same. Fig. 5

is a perspective view of a modified form of metal strap.

(1 represents the s11 utter-frame at one side, and b the wooden slats, 1) their pivotal ends, and b Figs. 3 and i, a reduced portion at one end of the slats. The vertical bar 0, I prefer to make of metal and to bend the same into a U-shaped form and to form bearings or openings at c at regular intervals along the edges of said bar.

(1 represents the metal strap, which, according to Figs. 1 and 2, is adapted to surround i the full width of the slat b, and said metal either between the slats and the vertical rod for moving the same or between the slats and the SlUlliElTltlllHi at their pivotal point a friction which shall be snl'licient to keep the slats in any desired position; and the object of my invention is, further, to provide a device which shall combine the desirable frictional qualifi cation just named and a further feature of adaptability to the slats of any window-blind,

which device shall be capable of moving each T set of slats as well as holding them in place at any desired position.

Myinvcntion consists in a metal strap that is adapted to pass around the individual slat, and said metal strap is made with pivotal jaw ends, each of which ends is formed with a half-pivot. The two half-pivots when brought together are adapted to be received in pivotal bearings formed in a U-shaped connecting bar, and said pivotal ends exert a friction in j the bearings of said bar, so as to hold the individual slats in place. made with pivotal half-bearings at a central point, which bearings are adapted to surround the pivotal end of the slat or to take its place The strap maybe I l i i strap may he of any desired width, and its surface may be ornamented or plated inany desired manner. These metal straps are preferably stamped up out of one piece of sheet metal, the strap (1 being formed with halfpivot-s or pivotal jaw ends 6 e, which ends are sectionally nearly a half-circle and are longer from end to end than the width of the strap. These half-pivots or jaw ends 6 e are adapted to be received in the openings 0' of the vertical bar 0, in which a bearing is formed, these ends being made large, so that, as shown in Figs. and t, the ends of the bearings c may come close in toward the slats b.

It will be seen from reference to Figs. 1 and that the edges of these pivotal j aw ends 6 e do not quite touch, it being a fact that the spring of the metal strap d acts to a greater or less extent to separate these pivotal jaw ends, and this spring action causes a friction in the bearings c between them and the ends e 6, so that in whatever position the slats b may be placed this frictional action acts to keep the slats steady and secure.

The straps cl shown in Figs. 3 and t are of shorter length than those shown in Figs. 1 and and in the frame of the shutter to produce a 2, and the same are adapted to surround the friction which shall retain the slat in place.

In the drawings, Figure 1 is a vertical section through a number of slats, showing the as heretofore described, the special object of l l l ff, as well as the ends e e, apart.

this construction heing to provide a groove, as it were, along the edge ot' the slats, into which the vertical bar 1' is adapted to he reeeived, where it will he more or less out of the way. The speeial advantage of this eonstruetion (shown in 'higs. land 2) is that; the straps and ertieal lHll' may he plaeed at an v desired position in the lengtho't the slats, either in the eenter or nearer either end, aeeoiding to the fancy ot' the party using them.

A moditied form of metal strap (7 (shown in Fig. is provided with halt-pivots or pivotal jaw ends e (1, similar to those hm'etotore deserihed, t he lower jaw end, e, having upturned a, slats I), and vertieal har e, of the metal ends 1 2, over whieh the halt-pivot or jaw e titsand laterally aeross the surt'aeeof whieh a eertain amount of movtanent is possible without liability of the parts separating, and this strap [1 is also made with pivotal hearingsjj", projeeting' from one edge of said strap at the eenter, f being a hal l pivot and f a halt pivot with an upturned end, I and it will he seen from l i .r.5,wl1ieh represents the strap as disengaged from the slat, thatthe strap possesses a springy quality, \vhieh keeps the hearings.

This st rap, l ig. 5, is adapted to he plaeed on the end of the slat, the heztringsff passing around the ends b of the slat, and the spring aetion of said. heztrings] f will produee in the shutterlrame u a it"rietion whieh will aet as well to keep the slats in plaee as the frietion of the ends e in connection with the vertical har I e, and it is possilile to use the strap 1/, Fit. 5, 5 upon a slat whose end I) may have been 5 hroken oil, the 'hearingsff forming one pivotal end for the slat as well alone as when sari-minding the end I).
